HINGE-JOINT.

Specification of Letters Patent.

Patented June 2a, reis.

Application filed March 11, 1914. Serial No. 823,869.

To all whom t may concern Be it known that I,'FRrrz ARTHUR AN- DEnsoN, asubject of the King of Sweden, and a resident of Milton, county of Rock,and State of Wisconsin, have invented certain new and usefulImprovements in Hinge- Joints, of which the following is a speciication.

This invention relates to hinge-joints, and more particularly to thatclass in which the joint comprises a pair of relatively movable hingemembers, each having a rollportion one concentric within the other,andwhich does not require a pintle proper.

The main objects of this invention are to provide an improved formofhinge-joint j rwhich shall be substantially frictionless in operation;which shall be adapted to serve as a dust-tight and light-tight joint;which shall be adapted for being formed mainly from sheet metal; whichshall be' convenient to assemble, and which shall be adapted to swingthrough a broad angular range.

An illustrative -embodiment of this invention isl shown in theaccompanying drawings, in which:

Figure 1 is an` end view with the hinge members turned to an angle of90o from each other. Fig. 2 is a similar view with the hinge membersturned into alinement 180D apart. Fig. 3 is a similar view, with thehinge members turned to lie fiat against each other. Fig. 4 is a sideelevation with the front of the roll portions of the joint broken awayat one end along the line .Al-A of Fig. 2- to show the end thrustbearings,

" lthe screw for the end block being removed.

Fig. 5 is a side view of the leftv hinge member shown in Fig. 4. Fig. 6is a side view of the right hinge member shown in Fig. 4. Fig-7 1s anaxial section of the hinge along the' line B-B of Fig. 2. Fig. 8 is asectional view similar to Fig. 7 but Lshowing a modification in whichthev anti-friction members'are omitted. Fig. 9 is a sectional viewsimilar to Fig. 7 but showing both ends of a long hinge with the middleportion brokenawayj'and illustrating a further modification in which asingle unitarystopmember is provided at each end. Fig. 10 isa side viewof a long narrow hinge adaptedto eX- tend continuously along the edge ofa door lid. or other hinged object. In the 4constructionshown in Figs.l-to 7, the hinge 1 comprises a pair of relatively means 6 are providedcomprising a pair of blocks 7 and 8 disposed side by side coaxiallyWithin the rolls and having circular runways 9 in their opposing facesfor bearing balls 10 disposed therein. The inner roll 5 (see Fig. 3) Awhich may be designated as the pintle-roll, is of semicylindrical shapewith its free edge or flange 14 turned diametrically inward for coactionagainst the inner surface of the outer roll 4, which may be designatedas the knuckle-roll. The roll 4 is of substantially cylindrical shapeand is formed with a medial longitudinal offset 15 opposite from theshank portion 17 of the same hinge member, whereby the part of the rolladjacent to the edge 14 is inwardly set somewhat from thev opposite partand whereby oppositely facing inner and outer shoulders 19 and 20 areprovided, which are adapted to serve as stops for the opposite edges 21and 22 respectively of the pintle roll 5 in opening and closing thehinge. The free edge 25 of the knuckle-roll 1s turned inward medially ofits length and provides an end thrust shoulder 28 which serves as a stopfor the inner stop block 7, which atl times may have rotative slidingContact therewith. The edge-flange 14 1s somewhat shorter than the hingeand the inner block 7 is carried rigidly thereby, a slot 30 beingprovided in said block for receiving an end 31 of the ange 14. The outerblock 8 is secured within the knuckle roll by any suitable means as ascrew 35. When thus assembled the parts are securely held in place withthe bearing balls between the stop members. In the form shown themembers2 and 3 have their Shanks 17 and 17 formed flat. It will beunderstood that the said Shanks may constitute the walls of a box or thelike as illustrated in Fig. 10, or may be of any desired form.

. In theconstruction shown in Fig. 8 the stop blocks 46 and 47 aremounted 1n the same way respectively as blocks 7 and 8 and are similarthereto except that no ball-races or balls are provided. For somepurposes this form will answer all practical requirements substantiallyAas well as the anti-fric-l tion `form having ball bearings.

'. In the construction shown in Fig. 9 the one at `each end similar toeach other and to the blocks 47 shown in Fig. 8, no inner blocks beingused. In this instance the ends ofthe inwardly turned flanges 14 and 25are both adapted at their ends for rotative contact with the blocks 47,and the inwardly turned flange 25 on the knuckle roll may be omitted,its presence not being required as the end blocks 47 and the flange 14on the pintle roll serve to prevent longitudinal movement. means at bothends is especially desirable where the hinge joint is very long, as incase it is used to provide a continuous hingejoint for extending alongthe whole length of the edge of a door or lid for rendering the samelight and dust tight. Moreover, the end stops impart a neat and finishedappearance by closure of the openings at-the ends of the rolls.

Concentric alinement of the rolls throughout their length is maintainedby the overlapping of the rolls 4 and 5 and the cooperative action ofthe flange 14.

The hinge parts may be assembled as follows: The block 7 is placed uponthe end of the ange 14. The hinge rolls are then telescoped together andthe outer block 8 inserted into the knuckle roll with the bearing ballsin place, `and is secured by means of the screw 35.

The operation of the hinge is as follows:

When the members are opened from the closed position shown in Fig. V3the rolls slide concentrically past each other and the free edge'of theflange 14 slides over the in ner surface of the knuckle roll 4, therebyassisting to hold the pintle roll in place. When the hinge is opened toits full extent,

the shank edge of the pintle roll is arrested by the stop shoulder 20.When the hinge is closed as shown in Fig. 3 the free edge of the pintleroll contacts with the inner shoulder 19 and the shank 17lies againstthe shank 17.

` Referring to Fig. 4, when the shank 17 is secured to a rigid supportas for instance a door frame, and the shank 17 has a load attachedthereto, as for instance a door, the vertical load will be carried onthe ball bearin s.

gAlthough a preferred specific embodiment of this invention is hereinshown together with certain modified forms, it v vlll be .understoodthat the invention is not l1mited to the precise. construction shown,and that some of the details may be altered or omitted without departingfrom the spirit of this invention;
